Assessment Process - Action Renewables

Assessment Process

The scope of this scheme is the supply, design, installation, set to work, commissioning and handover of the Microgeneration technologies. This scheme is open to companies involved in the supply, design, installation, set to work and commissioning of Microgeneration systems and technologies.

Assessment Process

The assessment takes the form of an independent,two-part assessment, normally conducted on the same day, this may be carried out by more than one assessor. Firstly an assessment of the company policies and procedures is carried out at the company headquarters, followed by at least one example installation site to ensure that the work is being undertaken in accordance with the company procedures.


Assessment begins with an opening meeting outlining the structure of the assessment for the day(s) the purpose of the assessment, the reporting method and the timing of the installation site to be visited. At the end of the day(s) a closing meeting will be carried out giving feedback on the assessment and the next steps.


The assessment of policies and procedures is carried out using document “MCS001 – Installer Certification Scheme Requirements”. This document contains 19 clauses (in Appendix A) with which the installer’s quality control systems are assessed against. Some of the requirements of MCS001 are included in ISO 9001 ‘Quality Management Systems’ (QMS), therefore if your organisation currently operates a QMS then you may already have many of the required procedures in place.


As a minimum Action Renewables will ensure the installation contractor has addressed the requirements detailed in MCS001 through documented procedures and systems. A summary of the requirements can be found here.

(Please note this is only a summary, you must read the full MCS001 and applicable MIS standard).



The following supporting documents will help your company prepare for assessment. Please read the relevant documents as they detail the criteria your company will have to meet in order to gain successful certification.

Consumer Protection

Under the terms of the MCS (see Clause 1 above), all applicants are required to sign up to a Consumer Code of Practice that has been approved by the Office of Fair Tradings (OFT) Consumer Code Approval Scheme. At the present time, the RECC (Renewable Energy Consumer Code) is the only organisation that offers a Consumer Code that meets the OFT Consumer Code Approval for Renewable Energy.


The Code was set up by the Renewable Energy Association in the UK. Their aim is to guarantee a high quality experience for consumers wishing to buy or lease small-scale energy generation systems for their homes. The Scheme has produced an information leaflet which is recommended for consumers considering installing renewables. Click here to download the leaflet. More information can be found on the RECC website, in particular installers must ensure that they comply with the Consumer Code.
